The mystery woman in the lives of Prince William and Catherine, Duchess of Cambridge, has finally been revealed.

According to multiple sources, Maria Teresa Turrion Borrallo has been selected by the royal couple as the new nanny for their son, Prince George of Cambridge.

“Maria is a full-time nanny, who started work with us recently, and will be accompanying the Duke and Duchess and Prince George to New Zealand and Australia,” the Daily Telegraph reported, quoting a Kensington Palace spokesman.

There has been much speculation about the identity of the new nanny, who has been photographed with Prince George in recent days, but who had remained anonymous until Thursday.

The Daily Mail, calling Borrallo a “Spanish Supernanny,” reports that she received her training at Norland College, “which was founded in 1892 and is famous for its traditional brown uniforms.”

The Norland website says its no-nonsense brown uniforms were developed to distinguish nannies as professionals — not housemaids.

“Along with its location, the curriculum at Norland has changed and progressed with the times to offer the most up to date academic childcare training courses and the highest practice standards in line with the latest research,” it explains. “Throughout its constant development Norland’s values have remained the same, with children being at the centre of all decisions and the Norland motto ‘Love Never Faileth’ being central to its values.”

And while there is tremendous interest in the new nanny and her background, the BBC quoted a Kensington Palace spokesman asking everyone to leave her alone: “As an employee of the Royal Household we would ask, please, that Maria’s privacy, and that of her family and friends, be respected. We will not be giving further details on Maria or her employment, except to say that the duke and duchess are of course delighted she has chosen to join them.”
